[Unextended and extended selective proximal vagotomy in the treatment of chronic uncomplicated duodenal ulcer].

Comparison of the results of selective proximal vagotomy (SPV) and extended selective proximal vagotomy (eSPV) in identical groups of patients with chronic uncomplicated peptic ulcer of the duodenum showed that early postoperative complications are encountered more frequently after eSPV. The decrease in gastric secretion is similar, delayed evacuation is more marked after eSPV. The ulcerous defect healed within equal periods, the late results were the same. In view of the above stated, the authors claim that patients with moderately increased gastric secretion (acidity below 45 mEq/hour) should be preferably treated by SPV; the indications for eSPV need further study.
